LPS system disk storage and memory
The system disks store the operating system software and the
system resources, such as fonts, forms, and graphics, you want
to load into memory for use during input processing. There are
several types of memory used with the LPS.
System disks
The 4050/4450 LPS has two standard 50 MB system disks.
Optional expansion of up to 200 MB in 50 MB increments is
available.
The 4090/4650 LPS has two standard 170 MB disks. Optional
expansion of up to two additional 170, 182, or 380 MB drives is
also available.
Font memory
Each character in a font set is composed of a unique pattern of
dots. Font memory stores the data representation of each
character in an individual memory location. If a job requires
multiple fonts, more font memory may be needed.

expandable to 16 MB.
